Title: Fixing bolts through conveyor belt - by using spikes receiving bolts which are hit to drive spikes through belt
IPC: F16G3/00
Filed: 1974-11-27
Abstract: This method of fixing transverse rows of bolts on to conveyor belts, for the attachment of for example buckets involves screwing each bolt (Bo) into a case hardened steel spike (12) which has a tapped hole of such a depth that a gap, the thickness of the belt, is left between the top of the spike and the underside of the bolt head. The spike is then driven through the belt, until the belt fits into the gap. When the bolt has been inserted, the spike is removed and replaced by the desired component. A fitting board which facilitates marking out the bolt positions on the belt guided between a scale and adjustable edge has a pivoting traverse bar with adjustable markers. A transverse slot allows the spikes to be driven through whilst the belt is supported on the board.

A standard number of apertures are provided in the mould, these being blocked off to suit requirements.
Patent FR-2272316-A1 (FR)
Title: Stop valve with pressure compensation - has cylindrical closure member movable axially into ring seal to close valve
IPC: F16K41/04
Filed: 1975-05-21
Abstract: The valve has a housing (2) having two axially spaced-apart ring seals (11, 12), an inlet (7) laterally into the space between the seals, and an outlet (10) through one (12) of the seals. The closure member (1) has a smooth cylindrical surface by which to extend through the other seal and, when open, extends short of the outlet seal, the fluid pressure force tending to urge the member axially into the fully open position being balanced by seal friction. To close the valve, the member is moved to engage the outlet seal when the fluid pressure can only act radially on the member and so becomes fully self-balancing.

Title: Insect larvae repellent cordifen - isolated from leaves of erlangia cordifolia by solvent extraction and used for plant protection
IPC: C07D493/14
Filed: 1977-07-13
Abstract: New substance cordifen from Erlangia cordifolia has structural formula (I) Cordifen is isolated by extraction of macerated leaves of Erlangia cordifolia, a plant growing in the Gikuyland region of Kenya. Cordifen has a repellent or 'anti-feedant' activity against insect larvae, and can thus be used for protecting crops. The antifeeds effect of cordifen is achieved without filling the insect larvae (they seek alternative foods when crops are sprayed with cordifen), so that the ecological balance is not disturbed. Effective results are obtd. when cordifen is incorporated into a carrier in a concn. of 70-100 ppm.

Title: Remote electronic switching system for telephonic network - comprises several processors using common bus line and data format
Inventor: YABE HIDEO
IPC: H04Q3/545
Filed: 1977-11-25
Abstract: A decentralised electronic switching system for a telephone network comprises several processors used separately for the different signalling systems. A common bus line is employed in conjunction with a common data format. Several processors are similarly employed for controlling switching of conversation circuits. A signalling system transmits and receives line signals and register signals to and from another switching exchange via send and receive lines. A switching network establishes exchange of connexions between conversation lilnes of interdistrict circuits. Switching is performed by a programmed switching processor. Opening and closing of switching relay contacts are signalled via signalling processors to caling processors via a common bus line.
